JP-A-8-61214

  The inventors of the present application conducted a test using an apparatus similar to the rotation maintaining apparatus according to Patent Document 1 in order to develop various systems using an apparatus capable of continuing rotation for a long time. However, with this type of apparatus, the rotation could not be continued for a long time.

  As a result of considering why the rotation maintaining device according to Patent Document 1 cannot continue the rotation for a long time, the rotational angular velocity of the slide weight caused by the difference in the rotational moment decreases due to friction between members such as between the slide weight and the guide body, It was found that the rotation cannot be continued for a long time because the decrease in the angular velocity due to the friction is rapid compared to the magnitude of the angular velocity due to the difference in rotational moment.

  For this reason, the inventors of the present application have intensively studied to develop a device that can maintain the shaft rotation over a long period of time by keeping the friction between members as small as possible and maintaining the difference in rotational moment as much as possible.

The present invention has been made based on such a problem, and an object thereof is to provide a rotating device capable of maintaining the rotation for a long time to the extent that it can be applied to various systems.

According to the present invention, the rotating device has a rotatable output shaft that is rotatably supported so that its axis is in a horizontal direction perpendicular to the gravity direction, and a rotatable shaft that is coaxially connected to the output shaft. A rotating plate member, and a plurality of rotating weight members that are pivotally supported by the rotating plate member at positions near the peripheral edge of the rotating plate member, and are rotatable in only one direction around the pivoted shaft, It is fixed at a stationary position coaxially with the axis of the output shaft, and a guide member having a partial arc-shaped peripheral end surface only on the side where the rotating weight member rises due to the rotation of the rotating plate member, and is rotatable on the rotating plate member A plurality of rotation engaging members that rotate when the outer peripheral end surfaces are guided by being engaged with the partial arc-shaped peripheral end surfaces of the guide members. Is a disk part having a rotation axis coaxial with the axis of the rotating weight member, and is fixed to the disk part. Each of the rotating weight members has an outer peripheral end surface of the rotating engagement member. It is configured to rotate in one direction by being engaged with and driven by the outer peripheral end face.

  The output shaft continues to rotate by the inertial rotational force of the rotating plate member. As the rotating plate member rotates, a plurality of rotating weight members pivotally supported by the rotating plate member rotate around the pivoted shaft, whereby the center of gravity position of the rotating weight member and the output shaft axis are rotated. The distance from the center changes and the rotational moment changes. Specifically, the rotation moment changes so that the rotation moment of the rotating weight member from the upper side to the lower side becomes larger than the rotation moment from the lower side to the upper side. That is, the guide member has a partial arc-shaped peripheral end surface only on the side where the rotating weight member rises due to the rotation of the rotating plate member, and when the guide member engages with the peripheral end surface and is guided, the guide member rotates. The member rotates, whereby the rotating weight member rotates, and the distance between the center of gravity of the rotating weight member and the center of the output shaft becomes shorter, and the rotational moment becomes smaller. On the other hand, the peripheral end surface of the guide member does not exist on the side where the rotating weight member descends due to the rotation of the rotating plate member. However, since it can rotate in only one direction, it does not rotate. Therefore, the distance between the center of gravity of the rotating weight member and the shaft center of the output shaft is kept long while descending, and a large rotational moment is maintained. Is done. In this way, the rotational moment of the rotating weight member from the upper side to the lower side becomes larger than the rotational moment from the lower side to the upper side, resulting in a difference in rotational moment, and this configuration has no linear sliding portion. Therefore, the loss due to friction is extremely small, and therefore the difference in rotational moment is effectively used for maintaining the rotation without causing a loss. With such a mechanism, the rotation can be maintained for a long time.

  When the rotating weight member is raised by rotation of the rotating plate member, the rotating weight member is rotated by driving the rotating engagement member, and when the rotating weight member is lowered by rotation of the rotating plate member, the rotating weight member is It is preferable to be configured not to rotate.

  The center of gravity of the rotating weight member when the rotating weight member is raised is configured to be closer to the rotation axis of the rotating plate member than the position of the center of gravity of the rotating weight member when the rotating weight member is lowered. Is preferred.

  It is also preferable that each of the rotating weight members is pivotally supported on the rotating plate member by a one-way bearing mechanism that rotates only in one direction.

  A pair of rotating plate members connected to the output shaft so that the rotating shaft is coaxial, and a pair of guide members fixed at a stationary position are provided, and a plurality of each of the pair of rotating plate members is provided. It is also preferable that the rotating weight member and the plurality of rotation engaging members are pivotally supported.

  It is also preferable to further include a flywheel member connected between the pair of rotating plate members so that the rotating shaft is coaxial with the output shaft.

  According to the present invention, the rotational moment of the rotating weight member from the upper side to the lower side is larger than the rotational moment from the lower side to the upper side, resulting in a difference in rotational moment. Since it does not exist, the loss due to friction is extremely small, and therefore the difference in rotational moment is effectively used for maintaining the rotation without causing a loss. With such a mechanism, the rotation can be maintained for a long time.

That is, the second rotating mechanism 30 includes a rotatable rotating plate member 31 that is coupled to the output shaft 10 so that the rotating shaft is coaxial, and an equal predetermined angle (this position near the peripheral end of the rotating plate member 31). In the embodiment, the rotary plate member 31 is pivotally supported at a position separated by 90 °), and four rotating weight members 32a to 32d that can rotate around the pivoted shaft and the output shaft 10 A substantially fan-shaped guide member (not shown) having a partial arc-shaped peripheral end surface only on the side where the rotary weight members 32a to 32d are raised by the rotation of the rotary plate member 31. ), And four rotation engagement members (illustrated) that rotate when the outer peripheral end surface is engaged with and guided by the partial arc-shaped peripheral end surface of the guide member. None).

The more detailed configuration of the four rotating weight members 32 a to 32 d in the second rotating mechanism 30 is the same as that of the four rotating weight members 22 a to 22 d in the first rotating mechanism 20.

  The flywheel mechanism 40 includes three flywheels 41, 42, and 43 that are attached to the output shaft 10 so as to be eccentric with respect to each other so that the positions of the center of gravity are deviated from the center of the output shaft 10. However, the center of gravity of these three flywheels 41, 42 and 43 is set so as to coincide with the center of the output shaft 10. The flywheel mechanism 40 may be constituted by three flywheels arranged coaxially, or may be constituted by one flywheel.

Hereinafter, the configuration of each element in the rotating device of the present embodiment will be described more specifically.

  The output shaft 10 is a rotating shaft made of steel, for example, and is supported so as to rotate smoothly by bearings 50a and 51a with bearings provided on support bases 50 and 51 by metal frames, respectively.

The rotating plate member 21 of the first rotating mechanism 20 is composed of a circular iron plate having an outer diameter of about 1000 to 2000 mmφ, and is mechanically fixed to the output shaft 10 by bolts or the like. The disk portions 22a _{1 to} 22d ₁ of the rotating weight members 22a to 22d are each composed of a circular iron plate having a diameter smaller than that of the rotating plate member 21, and the rotating plate member 21 is formed by the one-way bearing mechanisms 22a _{5 to} 22d ₅ . Are supported by each. Kaidotsumu member 22a~22d of the weight portion _{22a 2 ~22d} 2, respectively, are composed of circular iron plate of slightly larger diameter than the disc portion _{22a 1 ~22d} 1, the disc portion _22a 1 ~ by bolts or the like 22d ₁ are eccentrically attached to each other. Additional weight _{22a 3 ~22d} 3 of Kaidotsumu member 22a~22d each are composed of cut of semicircular iron plates, respectively mounted together periphery to the weight portion _{22a 2 ~22d} 2 by bolts or the like Yes.

The guide member 23 of the first rotating mechanism 20 is made of a substantially fan-shaped iron plate, is attached to a support base 52 made of a metal frame, and is fixed at a stationary position coaxial with the axis of the output shaft 10.

Each of the rotation engaging members 24a to 24d of the first rotating mechanism 20 is a circular tire having at least an outer peripheral portion formed of a rubber material, and is pivotally supported so as to be smoothly rotated by a bearing with a bearing (not shown). Yes.

The rotating plate member 31 of the second rotating mechanism 30 is made of a circular iron plate having an outer diameter of about 1000 to 2000 mmφ, and is mechanically fixed to the output shaft 10 with bolts or the like. The rotation weight members 32a to 32d, the guide member, and the rotation engagement member in the second rotation mechanism 30 are configured as the rotation weight members 22a to 22d, the guide member 23, and the rotation engagement member 24a in the first rotation mechanism 20. Thus, the guide member, its support base and the rotation engagement member are not shown.

  The flywheels 41, 42, and 43 of the flywheel mechanism 40 are each composed of a circular iron plate having an outer diameter of about 1000 to 2000 mmφ.

Next, operation | movement and an effect | action of the rotating apparatus in this embodiment are demonstrated using FIGS.

Since the operation of the second rotation mechanism 30 is the same as that of the first rotation mechanism 20 except that the rotation direction is reversed, in the following description, the operation of the first rotation mechanism 20 is performed. I will explain only. Note that the rotating device in the present embodiment is configured to rotate in a clockwise direction indicated by an arrow A in FIG.

  The output shaft 10 and the rotating plate member 21 rotate in the clockwise direction indicated by the arrow A by being initially driven by driving the electric motor or manually.

When the rotating weight members 22a to 22d are in the state shown in FIG. 3, that is, the rotating weight member 22d is on the upper side and is lowered from the upper side, and the rotating weight member 22c is on the lower side. When the moving weight member 22b is in the lower position and the descent is finished, the rotating weight members 22b to 22d are not driven to rotate by the rotation engaging members 24b to 24d. However, the rotation is prevented because the unidirectional bearing mechanisms 22b _{5 to} 22d ₅ are set to be rotatable only in the counterclockwise direction. As a result, the distance between the center of gravity of the rotating weight members 22b to 22d and the shaft center of the output shaft 10 is kept long, a large rotational moment is generated, and the rotation of the output shaft 10 and the rotating plate member 21 is promoted. Is done. On the other hand, Kaidotsumu member 22a in this case, although the state is rising, rotary engaging member 24a abuts counterclockwise outer peripheral end face 24a ₁ is a partial arc-shaped peripheral surface 23a of the guide member 23 of the Therefore, the rotary engagement member 24a rotates in the clockwise direction, whereby the rotary weight member 22a rotates in the counterclockwise direction. As a result, the distance between the center of gravity of the rotating weight member 22a and the center of the output shaft 10 is shortened, the rotational moment is reduced, and the force to weaken the rotation of the output shaft 10 and the rotating plate member 21 is reduced. .

When the output shaft 10 and the rotating plate member 21 are further rotated and the rotating weight members 22a to 22d are in the state shown in FIG. 4, that is, when the rotating weight members 22d and 22c are in the lowered state, The rotating weight members 22d and 22c are not driven to rotate by the rotation engaging members 24d and 24c. Therefore, the rotating weight members 22d and 22c try to rotate clockwise by gravity due to the deviation of the center of gravity, but the one-way bearing mechanisms 22d ₅ and 22c. ₅ is set so as to be rotatable only in the counterclockwise direction. As a result, the distance between the center of gravity of the rotating weight members 22d and 22c and the shaft center of the output shaft 10 is kept long, a large rotational moment is generated, and the rotation of the output shaft 10 and the rotating plate member 21 is promoted. Is done. On the other hand, the rotating weight members 22b and 22a are in a raised state in this case, but the outer peripheral end surfaces 24b ₁ and 24a _{1 of} the rotation engaging members 24b and 24a are partially arc-shaped peripheral end surfaces 23a of the guide member 23. The rotary engaging members 24b and 24a rotate in the clockwise direction and the rotary weight members 22b and 22a rotate in the counterclockwise direction. Thereby, the distance between the center of gravity of the rotating weight members 22b and 22a and the axis center of the output shaft 10 is shortened, the rotational moment is reduced, and the force to weaken the rotation of the output shaft 10 and the rotating plate member 21 is generated. To reduce.

When the output shaft 10 and the rotating plate member 21 are further rotated and the rotating weight members 22a to 22d are in the state shown in FIG. 5, that is, when the rotating weight members 22d and 22c are further lowered, These rotating weight members 22d and 22c are not driven to rotate by the rotation engaging members 24d and 24c. Therefore, the rotating weight members 22d and 22c try to rotate clockwise by gravity due to the deviation of the center of gravity, but the one-way bearing mechanism 22d ₅ and Since rotation is set only in the counterclockwise direction by 22c ₅ , rotation is prevented. As a result, the distance between the center of gravity of the rotating weight members 22d and 22c and the shaft center of the output shaft 10 is kept long, a large rotational moment is generated, and the rotation of the output shaft 10 and the rotating plate member 21 is promoted. Is done. On the other hand, the rotating weight members 22b and 22a are in a raised state in this case, but the outer peripheral end surfaces 24b ₁ and 24a _{1 of} the rotation engaging members 24b and 24a are partially arc-shaped peripheral end surfaces 23a of the guide member 23. The rotary engaging members 24b and 24a rotate in the clockwise direction and the rotary weight members 22b and 22a rotate in the counterclockwise direction. Thereby, the distance between the center of gravity of the rotating weight members 22b and 22a and the axis center of the output shaft 10 is shortened, the rotational moment is reduced, and the force to weaken the rotation of the output shaft 10 and the rotating plate member 21 is generated. To reduce.

  When the output shaft 10 and the rotating plate member 21 are further rotated, the rotating weight members 22a to 22d are in the state shown in FIG. 3, and the reference numerals are sequentially shifted, and the same operations and effects as described above are obtained. .

As described above, according to the rotation device of the present embodiment, the rotation moment of the rotation weight members 22a to 22d changes so that the rotation moment from the upper side to the lower side becomes larger than the rotation moment from the lower side to the upper side. . That is, the guide member 23 has a partial arc-shaped peripheral end surface 23a only on the side where the rotating weight members 22a to 22d are raised by the rotation of the rotary plate member 21, and engages with the peripheral end surface 23a for guidance. When the rotation engaging members 24a to 24d are rotated, the rotating weight members 22a to 22d rotate, and the distance between the center of gravity of the rotating weight members 22a to 22d and the axis center of the output shaft 10 is shortened. The rotational moment becomes smaller. On the other hand, since the peripheral end surface 23a of the guide member 23 does not exist on the side where the rotating weight members 22a to 22d are lowered by the rotation of the rotating plate member 21, in this case, the rotating weight members 22a to 22d are the rotation engaging members 24a to 24a. 24d does not rotate and tries to rotate in the opposite direction by its own weight, but it can rotate only in one direction, so it does not rotate. Therefore, the center of gravity position and the output shaft of the rotating weight members 22a to 22d are lowered during the descent. The state where the distance from the axis center of 10 is long is maintained, and a large rotational moment is maintained. As described above, the rotational moments of the rotating weight members 22a to 22d from the upper side to the lower side are larger than the rotational moments from the lower side to the upper side, resulting in a difference in rotational moments. Therefore, the loss due to friction is extremely small. Therefore, the difference in rotational moment is effectively used for maintaining the rotation without causing a loss. With such a mechanism, the rotation can be maintained for a long time.

In addition, in order to maintain rotation more smoothly, the rotation device of the above-described embodiment includes the first rotation mechanism 20, the second rotation mechanism 30, and the flywheel mechanism 40. A third rotation mechanism having the same configuration as that of the first rotation mechanism 20 may be provided. Further, the number of rotating weight members is not limited to four, and may be any number as long as it is two or more. In that case, the number of guide members is also adjusted to the number of rotating weight members.

  In the above-described embodiment, the first rotation connecting member 20 and the second rotation connecting member 30 have a structure that is inverted with respect to the output shaft 10. The structure may be shifted by an arbitrary angle.

  In the above-described embodiment, the support members 50 to 52 are configured by a metal frame. However, as a modified mode, the support members 50 to 52 may be composed of another material. For example, concrete or the like may be used as a constituent material.

An input terminal of a DC / DC converter or a power controller (not shown) is electrically connected to the output terminal of the AC / DC converter, and the output terminal is electrically connected to the battery 64. Further, the output terminal of the battery 64 or the power controller is electrically connected to the external terminal 65 via a DC / AC converter (not shown) so that AC generated power is sent to the outside via the external terminal 65. It is configured. Further, a control circuit 66 that controls the operation of the drive circuit 63 and the battery 64 is electrically connected.

The control circuit 66 drives the motor 61 at the time of initial driving of the rotary device, communicates the rotational torque to the output shaft 10 of the rotating device via the clutch 62, rotates the rotary device. Thereafter, the driving of the motor 61 is stopped, and the rotating device is rotated by inertia while the clutch 62 is disconnected from the rotating device . The generator 60 is driven by this rotation of the rotating device , the generated power is converted into direct current, voltage is adjusted, applied to the battery 64 and charged, and electric power is converted from the battery 64 to alternating current as necessary to adjust the voltage. And output to the outside via the external terminal 65. On the other hand, the control circuit 66 detects the rotational speed of the rotating device by a rotational speed sensor or the like (not shown), and when the rotational speed fluctuates or significantly decreases, the motor 61 is driven to generate the rotational torque. This is transmitted to the output shaft 10 of the rotating device via the clutch 62 to compensate for such fluctuations and decreases in rotational speed.
